用DDQ氧化10-10'单连接的二聚体，得到meso-meso，β-β，β-β三连接的2 H-可咯二聚体（每个可咯单元内有两个NH基），它们具有特征的（1）H NMR和吸收光谱，归属于它们的非芳香电子网络。这些2 H-可咯二聚体用NaBH 4还原成芳族3 H-可咯二聚体，其不稳定并且在暴露于空气时容易氧化回到2 H-可咯二聚体。双（锌（II））配合物的2 H-咔咯二聚体的合成和非芳香族锌（II）咔咯配合物的罕见的例子，其特征在于。
The oxidation of 10-10' singly linked corrole dimers with DDQ at low concentration in CHCl3 afforded meso-meso, β-β, β-β triply linked 2H-corrole dimers (with two inner NH groups in each corrole unit), which exhibited characteristic (1) H NMR and absorption spectra attributable to their nonaromatic electronic networks. These 2H-corrole dimers were reduced with NaBH4 to aromatic 3H-corrole dimers, which were unstable and easily oxidized back to the 2H-corrole dimers upon exposure to air. Bis(zinc(II)) complexes of the 2H-corrole dimers were synthesized and characterized as rare examples of nonaromatic zinc(II) corrole complexes.
